3.1 Baseline characteristics
A total of 200 patients who underwent conventional RVP (mean age 70.47 ±
12.01 years, 49.5% female) and 50 patients who underwent LBBAP (mean
age 68.75 ± 14.94 years, 50.8% female) were included in this study. A
comparison of baseline characteristics among the groups is summarized in
Table 1.
The distribution of pacing indications was as follows: In the
conventional RVP group, sick sinus syndrome was the most common
indication (54.0%), followed by atrioventricular (AV) block (46.0%).
In the LBBAP group, AV block was more frequent (81.5%) than sick sinus
syndrome (18.5%). The QRS duration was more likely to be narrow in the
conventional RVP group (62.0%) than in the LBBAP group (40.0%).
